#1 Fix for bug 552131 (segfault)

[Giovanni Beltrame]

This bug (a segmentation fault) is due to a call to che
method KComboBox.lineEdit() in , which works only if the
combo box is editable. Obviously it was not. In this case
lineEdit() returns 0, but popper makes no check and calls
the setText() method on it. The result is a nice segfault.
Fixed by making the box editable.
Also added some string manipulation function to make the
reply sent to the correct destination.
